1、施工方案的审查Brief discussion on construction plan review by directorThe construction plan is the core of the construction organization design, and also is one of the main documents guiding the site operation. Whether it is reasonable or not will directly affect the cost, duration and quality of the proje2、ct The advantages and disadvantages of the construction plan have direct and decisive influence on the economic benefit of the construction stage and the quality of the project As one of the main participants in the construction of the project, the Commissioner of the supervision department, the con3、struction program to seriously review, identify problems, pointing out, is related to the requirements of the laws and regulations, but also the director s obligations In this paper, the construction plan review, talk about their own ideas, for readers reference1 construction organization design and4、 construction plan contact and differeneeThe construction organization design is the basic technical and economic documents of construction enterprises in guiding a project preparations for the organization and implementation, is to the project (or single unit project) the construction preparation a5、nd the whole construction process, a comprehensive plan made in the aspects of human, financial and material resources, time, space, technology and organization the construction scheme of arrangement; construction unit or branch (sub) analysis of a construction technology and construction methods in6、 engineering, is through technical and economic conditions needed for construction process in the implementation of labor, materials, machinery costs and schedule in a reasonable organization analysis, construction technology and method is feasible and optimal choose from For some construction diffi7、culties and key sub - section projects, it is also necessary to draw up special construction plans1.1, the connection between the two(1) the relationship between the whole and local construction organization design is the overall construction plan, is local; construction plan is an essential part of8、 the project construction organization design, construction scheme from the construction organization design is of no significance, is to guide the construction of the(2) the relationship between guidance and guidance: construction plan must be carried out in the overall planning and overall deploym9、ent of the construction organization design; construction plan is always carried out in the preparation and implementation of construction organization design under the guidance of the1.2 the difference between the two(1) for different purposes: the construction organization design is the selection 10、method for the construction of the manpower and material resources, all aspects of time and space layout are arranged to clear the construction plan according to the requirements: the construction scheme is the preparation of concrete construction technology and method of a part, in order to ensure 11、the quality requirements and requirements safe and civilized construction.(2) the content of the preparation is different: the object of the construction organization design is the whole of the project It involves the construction of various aspects of the content, including project organization div12、ision, construction scheme, construction sequence, optimal allocation and save the use of various production factors and so on; the object of construction scheme is usually engineering division. The contents include the concept of the project, the difficulties in construction, the selection of the c13、onstruction methods and the specific construction methods and so on.(3) the emphasis is different: the construction organization design focuses on the plan, and the construction plan focuses on the imp1ementation.(4) the starting point is different: the construction organization design is from the a14、ngle of project management, and the construction plan is from the angle of project implementation layer2, the existing problems in the preparation of construction plansNow, some construction enterprises do not attach importance to the construction scheme, especially the small and medium-sized constr15、uction enterprises do not really understand the importance of construction plan, the specific circumstances so in the construction scheme combined with no project seriously for the preparation, so that the construction scheme has the following deficiencies and problems in the preparation and Impleme16、ntation process(1) the contents of most construction projects do not conform to the basic requirements of the state regulations, standards and technical specifications, nor are they in only one form according to the actual construction conditions and design drawings requirements From the content poi17、nt of view, this kind of construction plan is only some construction technology standards and other technical data for simple piling up.The construction plan is often used as a necessary data or only to be checked by the relevant department(2) for different engineering types, the construction plan f18、ailed to make a real analysis of the technical and economic indexes, and the diagrams, network design and calculation methods are all in a state of lack of scientific and unified standards(3) the construction market with the owners of construction enterprises (Contractor) put forward the increasingl19、y severe requirements, require the contractor to cope with the owners, not to consider the enterprise technical equipment and management level, not according to the actual situation of engineering, natural conditions and types of enterprises, develop truly can satisfy the construction plan of constr20、uction operation and construct!on management(4) the construction scheme can not play a guiding role in construction. First of all, the lack of technical staff construction scheme of theoretical foundation and concrete construction experience, according to set existing specification content copy prep21、aration, not for technical and economic analysis for the specific project object, does not have the function of guiding. Secondly, from the management mechanism, we have not always insisted on the construction plan as a guiding document, ignoring its authority, in the preparation, examination and ap22、proval, implementation, revision and other links, have not attracted enough attention. Therefore, the construction process can not really guide the role, can not be limited in certain resources and conditions, to achieve the technical and economic benefits of the project(5) the text of the construct23、ion plan is confused At present many staff computer application level and the writing level is not high, the construction program, or typo more typesetting confusion, but can not make good use of the chart, the construction scheme is not beautiful, hiberarchy is not clear, also affected the guiding 24、role of the construction scheme in a certain extent3 chief inspector on construction plan review of several pointsBecause of the different understanding of the construction plan, the content of the construction scheme compiled by different localities and units is also different To further understand25、 the role of the construction programme, the director shall examine the construction plan primarily from the following aspects3. 1 whether the basis of the construction plan conforms to the requirementsPrepared according to the construction plan are: construction drawings, construction organization 26、design, construction of the scene investigation to the data and information, construction and acceptance specification, unified standard for quality inspection and acceptance, safety operation procedures, construction and mechanical performanee manual, new technology, new equipment, new technology a27、nd so on. Some construction enterprises in the preparation of construction plans, the use of obsolete norms and standards, so that it can not guide construction operations.3.2, the content of the construction plan is complete?In order to strict construction plan preparation requirements, according t28、o the construction project management standard GB / T50362 - 2001 article 4.3.7, the construction scheme shall include the following contents (1) construction and construction sequence; (2) division of construction stages; (3) the construction method and construction machinery selection;(4) the cons29、truction safety design; (5) the contents and methods of environmental protectionGenerally speaking, the construction scheme for a single project system should include the following parts: 1) basis;2) item summary and construction conditions; 3) the overall arrangement of the construction; 4) constru30、ction method, technological process, construction sequence 5); quality standard; 6) quality control points; 7), security civilization and environment protection etc3. 3 does the construction plan meet the requirements of the relevant laws and regulations?(1) whether the construction plan meets the r31、equirements of compulsory provisions In addition to the construction characteristics of the project in accordanee with the construction process standards and organizations, but also to meet the requirements of the corresponding mandatory provisions For example, the technical specification for buildi32、ng foundation pit support (JGJ120 一 99) 3.7.5: in the process of foundation pit excavation, measures shall be taken to prevent the collision of retaining structures, engineering piles or undisturbed undisturbed scdl. Code for acceptance of construction quality of concrete structures (GB50204-2002) 433、.1.3: the sequence and safety measures for the removal offormwork and its supports shall be carried out in accordance with the construction technical scheme.Code for acceptance of construction quality of roof (GB50207 -2002 7. 1. 5) : a kind of must be laid firmly. Measures should be taken to streng34、then the seismic fortification area or the roof with a slope greater than 50% Technical code for safety of construction work at height (JGJ80 一 91) 3.1.1: operation on temporary high side, protective measures must be set up. Wai to(2) whether the construction plan meets the requirements of the regul35、ations on the administration of construction safety production. Such as: twenty-sixth construction units should prepare safety technical measures and construction site in the construction organization design scheme for the temporary use of electricity, to achieve a certain scale hazardous project pr36、epare special construction scheme, and affix the safety check result, the construction unit responsible for the technical and the general supervision engineer signed after the implementation. The full-time safety management personnel on-site supervision: 1) excavation and dewatering engineering; 2) 37、excavation engineering; 3) template engineering; 4) the lifting scaffolding engineering; engineering; 5) 6), demolition blasting engineering; 7) regulations of the competent administrative department of construction under the State Council or other relevant departments of the other risk large engine38、ering The construction units shall also organize experts to demonstrate and examine the special construction schemes for deep excavations, underground excavation works and high formwork projects in the projects mentioned in the preceding paragraph(3) whether the construction plan meets the requireme39、nts of the Construction Supervision Specification. For example, 5.4.8: the chief supervision eng in eer shall arrange for the inspector to inspect and inspect the construction process The key parts of the concealed engineering hidden process, construction process after the completion of difficult to40、 check, the discipline engineer shall carry out on-site supervision personnel arrangement Under normal circumstances, supervision enterprises will also require construction units to these sites, processes, preparation of construction programs.(4) whether the construction plan meets the requirements 41、prescribed by the local competent department In addition to the relevant laws and regulations and standards and regulations formulated by the state, local authorities have also issued many local requirements In the preparation of construction plans, should comply with their requirements3. 4 construc42、tion plan commonly used in the calculation of the review(1) the review of formwork calculation: the cost of formwork is about 1 / 3 of the cost of concrete works When reviewing the scheme, the design and calculation of the formwork structure should be reviewed from the practical, safety and economic43、 aspects, and the load, load combinations and structural rigidity of the formwork shall be in line with the requirements(2) calculation of exterior frame review: 1) calculation of lateral rod strength; 2) calculation of longitudinal strength;3) connecting fastener anti slide bearing capacity calcula44、tion;4) calculation of rod stability; 5) wall calculation; 6) vertical bearing capacity calculation of pole foundation.(3) temporary power consumption calculation review: the power supply plan and power supply system of construction electricity should be reviewed to ensure the safety and reliability45、 of construction electricity Some construction enterprises have no understanding of the nature of power consumption and power factor in the field construction, which results in errors in calculation, and hidden dangers for temporary construction electricity, which results in unnecessary losses Durin46、g the review, the chief executive should review the calculation of the capacity and the capacity of the equipment(4) temporary water use calculation review: mainly from the water consumption determination, water supply pipe diameter determination and the selection of water pumps in several aspects o47、f review.(5) calculation and review of receiving platform: review should be done mainly from horizontal horizontal bar, calculation of skid resistance of connecting rod and calculation of intermediate stay pole3. 5 review some new technologies, processes and materials usedSome construction units, in order to improve the progress and quality of construction, the use of new technologies, new processes, new materials As director, we should conduct innovative construction projects
